This package provides a Python interface to the library, enabling fast computation of nonuniform discrete Fourier transforms to specified precision in one, two, and three dimensions. It supports transforms of type 1 (nonuniform to uniform), type 2 (uniform to nonuniform) and type 3 (nonuniform to nonuniform). For more information, see the online documentation.
